Actually, it is an RTFM... From the manpage of pgbuiltin (my postgres version is 6.2.1): For the date_part() and date_trunc() functions, arguments can be `year', `month', `day', `hour', `minute', and `second', as well as the more specialized quantities `decade', `century', `millenium', `millisecond', and `microsecond'. date_part() allows `dow' to return day of week and `epoch' to return seconds since 1970 for datetime and 'epoch' to return total elapsed seconds for timespan.
